49e3307da0 wifi: cfg80211: stop exporting wext symbols
CFG80211_WEXT_EXPORT is no longer needed, if we only make
ipw2200 return the static name for SIOCGIWNAME itself.

4991d2e7ad staging: don't recommend using lib80211
No longer document drivers should switch to lib80211,
they really should never have done that. While at it,
also remove the recommendation to use cfg80211, if it
switches to mac80211 then it implicitly uses cfg80211
but doesn't need to do anything about that, normally.

There's already much code in libipw that used to be shared
with more drivers, but now with the prior cleanups, those old
Intel ipw2x00 drivers are also the only ones using whatever is
now left of lib80211. Move lib80211 entirely into libipw.

bd9813d13b wifi: cfg80211: check radio iface combination for multi radio per wiphy
Currently, wiphy_verify_combinations() fails for the multi-radio per wiphy
due to the condition check on new global interface combination that DFS
only works on one channel. In a multi-radio scenario, new global interface
combination encompasses the capabilities of all radio combinations, so it
supports more than one channel with DFS. For multi-radio per wiphy,
interface combination verification needs to be performed for radio specific
interface combinations. This is necessary as the new global interface
combination combines the capabilities of all radio combinations.

5a4d42c168 wifi: wl1251: Use IRQF_NO_AUTOEN flag in request_irq()
As commit cbe16f35bee6 ("genirq: Add IRQF_NO_AUTOEN for request_irq/nmi()")
said, the code below is subobtimal. IRQF_NO_AUTOEN flag can be used by
drivers to request_irq(). It prevents the automatic enabling of the
requested interrupt in the same safe way. With that the usage can be
simplified and corrected.

	irq_set_status_flags(irq, IRQ_NOAUTOEN);

ea11a89c3a wifi: brcmfmac: add flag for random seed during firmware download
Providing the random seed to firmware was tied to the fact that the
device has a valid OTP, which worked for some Apple chips. However,
it turns out the BCM43752 device also needs the random seed in order
to get firmware running. Suspect it is simply tied to the firmware
branch used for the device. Introducing a mechanism to allow setting
it for a device through the device table.

====================
pull-request: can-next 2024-09-11

The first patch is by Uwe Kleine-König targets all CAN platform driver
and switches back the remove function to struct
platform_driver::remove().

A patch by Stefan Mätje fixes the help text of the ESD USB driver.

Jake Hamby's patch masks an unneeded interrupt in the m_can driver.

The last 2 patches target the rockchip_canfd driver. Arnd Bergmann's
patch reworks the delay calculation for the timekeeping worker, a
patch by me fixes the decoding of the error code register.

7bb50f30c1 Merge branch 'net-fib_rules-add-dscp-selector-support'
Ido Schimmel says:

====================
net: fib_rules: Add DSCP selector support

Currently, the kernel rejects IPv4 FIB rules that try to match on the
upper three DSCP bits:

 # ip -4 rule add tos 0x1c table 100
 # ip -4 rule add tos 0x3c table 100
 Error: Invalid tos.

The reason for that is that historically users of the FIB lookup API
only populated the lower three DSCP bits in the TOS field of the IPv4
flow key ('flowi4_tos'), which fits the TOS definition from the initial
IPv4 specification (RFC 791).

This is not very useful nowadays and instead some users want to be able
to match on the six bits DSCP field, which replaced the TOS and IP
precedence fields over 25 years ago (RFC 2474). In addition, the current
behavior differs between IPv4 and IPv6 which does allow users to match
on the entire DSCP field using the TOS selector.

Recent patchsets made sure that callers of the FIB lookup API now
populate the entire DSCP field in the IPv4 flow key. Therefore, it is
now possible to extend FIB rules to match on DSCP.

This is done by adding a new DSCP attribute which is implemented for
both IPv4 and IPv6 to provide user space programs a consistent behavior
between both address families.

The behavior of the old TOS selector is unchanged and IPv4 FIB rules
using it will only match on the lower three DSCP bits. The kernel will
reject rules that try to use both selectors.

Patch #1 adds the new DSCP attribute but rejects its usage.

Patches #2-#3 implement IPv4 and IPv6 support.

Patch #4 allows user space to use the new attribute.

Patches #5-#6 add selftests.

2cf630034e ipv6: fib_rules: Add DSCP selector support
Implement support for the new DSCP selector that allows IPv6 FIB rules
to match on the entire DSCP field. This is done despite the fact that
the above can be achieved using the existing TOS selector, so that user
space program will be able to work with IPv4 and IPv6 rules in the same
way.

Differentiate between both selectors by adding a new bit in the IPv6 FIB
rule structure that is only set when the 'FRA_DSCP' attribute is
specified by user space. Reject rules that use both selectors.

c951a29f6b net: fib_rules: Add DSCP selector attribute
The FIB rule TOS selector is implemented differently between IPv4 and
IPv6. In IPv4 it is used to match on the three "Type of Services" bits
specified in RFC 791, while in IPv6 is it is used to match on the six
DSCP bits specified in RFC 2474.

Add a new FIB rule attribute to allow matching on DSCP. The attribute
will be used to implement a 'dscp' selector in ip-rule with a consistent
behavior between IPv4 and IPv6.

For now, set the type of the attribute to 'NLA_REJECT' so that user
space will not be able to configure it. This restriction will be lifted
once both IPv4 and IPv6 support the new attribute.
